Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine if consumption of bagels made with resistant starch for 8 weeks can improve markers of type 2 diabetes, colon cancer and satiety in adults.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Using a randomized, double-blind crossover study design, we will determine the effect of consuming bagels made with resistant starch daily for 8-weeks can reduce the risk of type 2 diabetes and colon cancer in an adults who are at an increased risk for type 2 diabetes. Additionally, we will compare the satiating effect of these bagels to that of a standard bagel.
